respectively, of Honolulu, Hawaii, and of San Francisco, in the county of San Francisco and State of California, havelinventedv a new and Improved Sprinkler, of which the follow- Ingfisa full, clear, land exact descri tion.

Our invention relates to sprink ingv appa-l ratus,`and more particularly to that .adapted for use in watering lawns and the like.

It has for its principal object the provision of a movable sprinkler in which the direction of rtation is automatically reversed and in ,which therange of this movement maybe varied.

Reference is to be had to the accompanying drawings, forming a part of this specification, inwhich similar characters of reference indicate corresponding parts in all the views.

Figure 1 shows one embodiment of our invention in side elevation. Fig. 2 is an enlarged top plan view thereof with the cover of the head removed and parts broken away and in Section, and Fig. 3 is a partial transverse vertical section on the line 3 3 of Fig. 2.

10 designatesv a standard lliavinglegs 11, preferably provided with pointed extremities to engage the groundand hold the apparatus y in position. This standard 1s hollow and open at its upper extremity to furnish a supply-conduit. which is made a branch pi 13 for connection with'a hose 14. Threa ed upon the upper end of the standard is a cou 1mg 15, having screwed into it a nipple 16, a out which, resting upon the couplin ,is a washer '1 7. U on this washer bears t e neck 18 of a hol ow head 19, which is thus stepped for rotation about the standard and which continues the conduit furnished thereby. From opposite-- sides of the 'head at 4one side of the axis extend opposite outlet-pipes 2O 20, having at their outer extremities elbows 21 from which prolject jet-nozzles 22. These nozzles extend in the same general direction, so that the impulses produced by the delivery of the jets oppose oneanother, thus tendmg `-to effect rotation in opposite directions. The angle of these jet-nozzlesis preferably somewhat upward from the horizontal to more eectively distribute the discharge. The jet-pipes are shown as extending into the head at 23,l

t includesa T 12, into` where they are rovided with inner conical' surfaces 24, furnishing seats for similarly tapered valves 25 25. These valves have a common support in the form of a connecting- Y rod 26, whichK rojects beyond the valves at 27 to aid in ho ding them against lateral displacement Across the upper extremity of the nipple 416 is supported Ia bridge .28, from which rises a spind e'29. Surrounding this spindle and resting upon the bridge is a hub y30, from which rojects anarm or operatin lmember 31. T is arm has a longitudinal s ot which embraces the rod 26, and surrounding the l rod at each side of the `arm and having their ends contacting therewith and with thevalves are spiral sprin 31", which tend to hold the arm 1n a centra position between the valves. From one side of the lower portion ofthe hub is a projection 32, which may contact with a projection 33 from the upper end of the nipple 16. At the upper portion of the hub is a projection 34 for coaction with a rojection 35, depending from a plug 36, Whlch fits with a nec or cap 38, threaded into the to of the head to furnish aclosure therefor. Tll axial bore bearing upon a reduced end portion 39 of the spindle 29 and may be adjustably .iixed in position with relation to the head by a nut 40, threaded upon the upper end of the spindle. Avflange 41 upon the plug extends over the end of the neck.

-Assuming the plug to be so fixed in place that its projection lies in substantially vertiin one direction, thus distributing the ilow over a circular area... This continues until the opposite hub projection contacts with the companion projection either upon thenipple or plug, which forces the arm against the spring of the o en valve, moving it to its seat t er companion jet-pipe. The

valve for each outlet, said valves having a through the dierent outlets,I and means 4valve for each outlet, and means operable by compressed under the momentum of the rotating elements and exerts its expansive force to start the movement of the head in the opposite direction. The flow now being through the other jet-nozzle, continues this opposite rotation until contact between the other pairr of projections occurs, when the operation is repeated, this taking place intermittently as long as liquid under vpressure is supplied to the standard.' 'As described a substantially complete circle has been covered by the jets. .If it is desired that a less area shall be sprinkled, the nut'40 is loosened and the. lug turned'until its projection has moved t ough a greater or less angle from The arm now is capable of less movement before tengages one of these projections, and in this manner anyarc of rotation may be secured and the duration of How roporticnately varied,

It W be obvious'that as but one jet-pipe is operating at a time the delivery will e over a greater area than when a plurality are in use, thus increasing the field of effect of the apparatus. -Y v Having thus described our invention, we claim as new and desire to secure by Letters Patentf l 1. The combination With a movable conduit, having jet-'outlets o posing. the rotary effects of one another, ofp valves in the jeto'utlets for intermittently directing the flow whereby the movement of the conduit may operate said valves.

2. The combination Witha movable conduit having a plurality of jet-outlets, of a the movement of the conduit for shifting the valves. l 3. `The combination with a rotatable conduit having a plurality of jet-outlets, of a common support, and means whereby the rotation of the conduit may shift said valves.

4. The combination with the standard, of a molvable ieaddrotatapleghereon, means for su `n i ui to t e cad, o osite jetpigsyllealing from the head, valffges for directing the flow alternately through the jet- I pipes, and means whereby the movement of j the conduit may operate said valves. 5

5. The combination with a standard of a i hollow head'rotatable thereon, means for sup# lying liquid to thev head, opposite jet-pipes eading from the head, movable means for closing'y the pipes, and contact projections carried b the standard and head for coperating wit said closing means.

6. The combination with a standard, of a hollow head rotatable thereon, means for supplying liquid to the head, 'opposite jet-v pipes leading from the head, movable means forclosing the pipes, contact projections carried by the standard and head for coperat-l ing with said closing means, -.and means for adjustably xing the position of one of the projections.

7. The combination with a standard, cfa hollow head rotatable thereon, means' for pipes lea ing from the head, a valve for controlling they opening through each pipe, and a movable member carried by the standard and cooperating with the valves.

8. The combination with a standard, of a hollow head rotatable thereon, means for supplying liquid to the head, opposite jetreaction of the water issuing therefrom, said tube having an opening, means adapted to alternately connect said opening with said nozzle and to cut it off therefrom, and means for automatically moving said, nozzle backwardly in itsfpath.
